How can older rocks be found above younger rocks in a cross section?

There are two possible explanation. In one cases the underlying younger rock could be an igneous intrusion, formed when molten rock was injected into pre-existing rock and then cooled. Another explanation might be that the beds were overturned as the rock was deformed and tilted.

Older rocks can be found above younger rocks in a cross section due to processes like faulting and folding. Faulting occurs when rock layers break and move along a fault plane, causing older rocks to be displaced above younger rocks. Folding occurs when rock layers are subjected to compressive forces, resulting in older rocks being pushed up and over younger rocks. These geologic forces create the observed order of rock layers in a cross section.

Is it true Older sedimentary rocks are usually found beneath younger ones?
If the strata layers are folded or tilted then the older rocks can be found on top of the younger rocks in a cross-section.
How can you determine the relative age of a rock layer by looking at a cross section?
In the cross section, examine the different layers. The layer at the very bottom will be the oldest, and the one above would be slightly newer, and the one above that even newer, and so on, until the most recent rock layer is found at the top. Therefore, the layer you study will depend on those features. If you know the age of one layer, you will know the relative age of another.
Why the age of a fault is younger than the rocks in which it is found?
100 year old
Why is the Mid Atlantic ridge younger than the rock found on the edge of the continents?
Because it is

How can older rocks be found on top of younger rocks in a cross-section?

What is the vertical cross section of a cone?
The vertical cross section of a right vertical cone is a triangle if that cross section is taken from the vertex. Any other vertical cross section will reveal a hyperbola (with endpoints on the base of the cone). A link can be found below.
How do you find the cross section volume of a trapezoid with a change in slope?
The cross section volume of a trapezoid is found between 0 and 2.0.
Where can you get a cross section of leopard and koala?
I found a really good cross section at this website: www.koalaswim.com The website is Koala South Western Internal Medicine.
An unconformity is found in a geologic cross section What does this indicate happened in this area?
Erosion
What is the volume of the prism describe how you found the volume?
To find the volume of a prism you first need to know the area of cross section. Then, Volume of prism = area of cross section x length.
What tissue covers the outermost part of the cross section of aristolochia?
Sclerenchymatous cortical tissue covers the outermost cross section of the aristolochia vine plant found primarily in the Blue Ridge Mountains.
Where is the respiratory center found?
In the pons, a section of the brain stem right above the medulla.

Where is the secondary respiratory center found?
In the pons, a section of the brain stem right above the medulla.
Were the Ark of the Covenant Jesus' Cross of Calvary or the Holy Grail ever found?
No, but throughout history, many have said they have found at least one of the above.
What are the two factors on which the resistance of a cylindrical conductors depends?
For conductor the resistance (R) is directly proportional to the length (L) of the conductor, and the area of cross-section (A). When you stretch the conductor to increase its length, its area of cross-section will decrease. The decrease in area of cross-section can be found in the following way: The volume of the cylinder will remain same. The initial volume of the cylinder is = A Х L Suppose, the area of cross-section becomes A/ and the resistance becomes R/. Hence, the resistance increases 4 times. Hope this helps you, Keep posting and have a nice day!
